ORA-01000 Max Cursors even when closing

Question

When I execute the following code, the number of open cursors increases by 2, even though I am disposing of the reader, command and connection.
long returnValue=0;               
OracleConnection myOracleConnection = null;
OracleCommand cmd = null;
OracleDataReader reader = null;
try
     myOracleConnection = new OracleConnection(strDBConn);
     myOracleConnection.Open();
     cmd = new OracleCommand(spGetNextSequenceNo, myOracleConnection) ;
     cmd.CommandType = CommandType.StoredProcedure;
     cmd.Parameters.Add(prmSystemType,intSystemType);
     cmd.Parameters.Add(prmSection,strSection);
     cmd.Parameters.Add(new OracleParameter("rc1", OracleType.Cursor)).Direction = ParameterDirection.Output;
     reader = cmd.ExecuteReader();
     if(reader.Read())
          int colCount = reader.GetOrdinal("NextSequence");
          returnValue = reader.GetInt64(colCount);
     return returnValue;
catch(Exception myException)
     return 0;
finally
     if( myOracleConnection != null )
          myOracleConnection.Close();
          myOracleConnection = null;
     if( cmd != null )
          cmd.Dispose();
          cmd = null;
     if( reader != null )
          reader.Close();
          reader.Dispose();
          reader = null;
the stored procedure being called is given below
CREATE OR REPLACE PROCEDURE SPCRISPGETTRANSFORMFIELDS(
     RC1     IN OUT crisp.globalPkg.RCT1) AS
/* Force:DPP      Version: 1.0.5      DateModified: 2003:07:25 */
     CURSOR curExtractsTrnsfrmLook IS
          SELECT
               name
          FROM
               CRISP_SYS_EXTRCTS_TRNSFRM_LOOK;
     myRowVariable     curExtractsTrnsfrmLook%ROWTYPE;
BEGIN
     OPEN RC1 FOR
          SELECT
          FROM
               CRISP_SYS_EXTRCTS_TRNSFRM_LOOK;
     OPEN curExtractsTrnsfrmLook;
     FETCH curExtractsTrnsfrmLook INTO myRowVariable;
     IF curExtractsTrnsfrmLook%NOTFOUND THEN
          raise_application_error(-20999, 'ERROR encountered when retrieving rows from CRISP_SYS_EXTRCTS_TRNSFRM_LOOK (spCRISPGetTransformFields)');     
     END IF;
     CLOSE curExtractsTrnsfrmLook;
EXCEPTION
     WHEN OTHERS THEN
          IF curExtractsTrnsfrmLook%ISOPEN THEN
               CLOSE curExtractsTrnsfrmLook;
          END IF;
          RAISE;
END SPCRISPGETTRANSFORMFIELDS;
I am closing the cursor checking for the existence of any rows, but even this cursor appears in the v$open_cursor view.
Can anyone explain why this is?

Answer 1

I am having the exact same problem and am also closing and disposing the datareader and the connection. have you heard anything?
